  • Historic models

    The master watchmaker Julius Assmann is considered one of the founders of the art of watchmaking in Glashütte. His extremely precise “observation watches” soon became indispensable navigational instruments for captains, pilots and explorers like Roald Amundsen. The design of the Senator Observer is based on the timepieces from the workshop of Julius Assmann.

  • Everything at a glance – always

    The Senator Observer presents a small seconds dial at 9 o’clock and a power reserve indicator at 3 o’clock. Glashütte Original’s compelling Panorama Date is positioned at hour 6 on the dial. A finely drawn railroad chapter ring frames the Arabic numerals.

  • An exceptional movement

    The Calibre 100-14 is an exquisitely decorated automatic movement with a 55-hour power reserve. Traditional observation watches used hand-wound movements; today Glashütte Original makes use of a contemporary automatic movement to ensure maximum comfort for the wearer. The ‘Ab Auf’ indicator, for example, represents a true power reserve, rather than a simple indication of running time.

  • The spirit of discovery in three versions

    The stainless steel model is available with three dial variations: the dials in silver and grey have three different coats of lacquer and feature a striking, finely worked, grained surface. The matte black version is particularly eye-catching thanks to its glowing SuperLuminova highlights and historic font.

The waves of time

With the Senator Observer, a sophisticated deck watch, Glashütte Original evokes the exciting history of navigation at sea. Marine chronometers and observation watches were made in Glashütte until well into the 1970s, which testifies to the continuing production of precious timepieces even under challenging circumstances.
